Pictures of the small CNC Drilling and Milling Machine

The CNC machine in
its first form. The Z-axis still has no drive, the holes had to be drilled
by hand turning the knob on the Z-axis top.
The CNC machine while
drilling the MÁV Class
326 model tender's framesides. The workpiece
is fixed by screws to the XY table.
The CNC machine while
drilling. There is a particle board below the brass sheet.
The CNC
machine makes flutes into a nickel silver sheet. After drilling the crank
holes they will be fluted connecting rods.
The same job from another view. Here you can
see the CNC machine's guide rails and the stepper motors.
The frameside of the
MÁV Class 326
steamer's tender. The large holes are the openings, they will be cut
by piercing saw. The pattern of the small, 0.4mm (0.016") holes, well visible
in the zoomed picture,
are for the rivets. After cutting out the frameside 0.4mm diameter wires
will be glued into these holes and they will be grinded flat.
These are the cylinder cover disks for the
MÁV Class 342 model.
The hole pattern was made by the CNC Drill machine. These 0.4mm (0.016")
holes will be fillled out by a brass wire of the same diameter that is glued
in the hole. It will be cut and grinded to have a length of 0.5-0.7mm
(0.02-0.025") above the disks imitating the cover bolts. The disks are cut
off the brass sheet by a lathe.
This is the uncut sheet that contains the main
and connecting rods for the
MÁV Class 326
steamer. The flutes and the holes are already finished, and the sheet
is scribed for cutting out the outlines.
